PATENT MEASURING AND DISPENSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 594,196, dated November 23, 1897.

Application filed July 22, 1896. Serial No. 600,128. (No model.)

exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in liquid dispensing and measuring apparatus, and has more particular relation to such apparatus as is employed for measuring and dispensing milk.

The invention consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 represents a central Vertical section through the devices embodying my invention. Fig. 2 represents a top plan view of the same. Fig. 3 represents a modified form of my invention. Fig. 4 represents a top plan view of the agitator.

Fig. 11 represents a broken detail vertical section of a portion of a refrigerator with my invention applied thereto. Fig. 12 represents a central vertical section through a modified form of valve-seating devices.

A in the drawings represents the can or receptacle to which my measuring and delivery apparatus. is applied.

B represents the pumpcylinder; O, the cover to which it is attached; D, the deliveryspout and E the agitator.

. The can A is of any well-known and desirable form and is preferably provided with the usual flanged and flaring top rim a. The cap 0 is held upon the can by means of a clamping device F. This device comprises a plate f, secured to the inside of the cover and provided with two pendent spaced lugs f f, between which is pivoted a clamping-block f This block is provided upon its outer face with a clamping-plate which is adapted to fit the neck of the can and is provided with a screwthreaded stud f 3 upon its back for securing it to said'clamping-block, so that it may be ad- 3' usted thereon to fit different-sized cans. The block f is forced forward against the neck of the can by a cam-lever f that is pivoted upon the lower ends of the lugs f f. This cam is provided with a square corner j, which is adapted to cause the can to spring into place.

and lock itself against the clamping-block and thus hold the cover firmly upon the neck of v the can. The cover 0 is provided at its center with an auxiliary cover 0, secured thereto and having a pendent flange c. The pumpcylinder B is secured to this latter cover by a hollow screw threaded stud b, that passes through an aperture in the center of the auxiliary cover and is held in position by a hollow nut 12. The cylinder B is provided with a removable top 12 a piston b and a piston-rod 6 connected to the latter and passing up and outthrough the top of the pump-cylinder and the auxiliary top. The piston b comprises two spaced plates 1) b respectively, with a packing 6 between them about their periph-' eries. These plates are held together by the lower screw-threaded end of the pistonrrod,

which passes through them. This piston-rod is slotted longitudinally in a stair-step fashion, as shown in Fig. 3, so that its movements may be limited by a catch-rod H, secured upon the top of the cover. This catch-rod is projected more or less into the slot in the piston-rod, so as to be engaged by the proper projection of the slot, by a lever h, that is pivoted to the top by a pin h, that works through a slot in the same. The opposite end of the said lever is adapted to be secured in the desired notch in a segmental adj Listing-rack 71. by means of a bow-spring h secured to the under side of the same and engaging the notches in the said rack. By means of this adjustment the action of the piston can be so regulated that it will take up and deliver only a certain quantity of the liquid, which has previously been determined by the position of the lever upon the segment. The piston-rod is connected at its upper end to an operating-lever I, that is pivotally mounted upon the cover of the can bya pivoted link e'. A pendent tube K is attached to and communicates with the lower end of the pump-cylinder and extends to the bottom of the can. This tube is recessed at its bottom, so that although it may rest upon the bottom of the can it will still take up the liquid therein. The upper end of the tube is provided with an upwardly-opening valve 70, that is normally kept seated by a spring 76. A delivery-tube Z is also connected to the lower part of the cylinder and is provided with an upwardly-opening valve Z, that is seated upon a ground seat P, which in turn is seated in the flaring end of the tube Z and held in position by the lower conical end of the upper portion of said tube Z, said portion screwing into the lower portion and forcing said ground plate down upon its seat. The valve Z is held normally down upon its seat by a spring Z The upper end of the vertical portion of the tube 1 is secured in the cover of the can by means of two lock-nuts Z and Z respectively. The upper end of the said tube is provided with a conical seat, in which the lower conical end of a spout-receiving sleeve Z is secured. The spout D is adapted to screw into the screw-threads'with which the upper end of the sleeve 1 is provided. This spout is provided at its end with a cover (1, held in position by a spring-clip d, to prevent dirt or other foreign substances from entering the tube. The inverted-saucer-shaped agitator E is applied about the pendent tube K, so as to slide freely thereon, by means of a rubber sleeve 6, a rod E being attached to said agitator and extending up and out of thecovcr of the can and provided with a bandle 6', whereby it may be operated. This agitator prevents the milk and cream from separating, with a result of good milk being drawn from the can at the bottom, whereas if the milk were allowed to stand the cream would rise to the top, and the result would be that poor milk would be drawn from the bottom. provided in the cover of the can for filling the same when desired.

In the modified form of myinvention shown in Fig. 3 I have done away with the discharge-tube Z and draw the liquid directly through the cylinder.

In this application of my invention a pendent tube M is suitably attached tothe bottom of the cylinder and communicates therewith. This tube isof similar construction with the tube shown in Fig. 1 and is provided with a similar spring actuated upwardly opening valve m. The piston in this case is provided with an upwardly-openin g valve m, normally held down bya spring m. The piston is subspective parts by screw-threads.

A suitable covered aperture 0 is stantially like that shown in Fig. 1, with the exception that the two parts are held together by screw-threaded flanges m formed thereon. The upper portion of the piston is apertured at m to allow the liquid to pass therethrough at this point. The deliveryspout N is attached to the upper end of the cylinder by a conical nut n, seated in a conical projection a, formed on the cover of the cylinder, said nut being held in position by a binding-nut n .in a manner similar to the attachment of the spout in Fig. 1. The upper end of the piston-rod passes through an aperture 01 in the top of the spout and is provided with a suitable packing n for preventing the escape of the liquid at this point.

The can is provided at its bottom with crossstrips (t, so attached thereto that the operators foot can be placed thereon to keep the can firmly in position when the pump is being operated.

The can illustrated in Fig 3 is of slightlydiiferent construction from that shown in Fig. 1, and its cover is attached thereto by suitable hasps and staples 0 and 0, respectively.

In the form of my invention shown in Fig. 3 the piston-rod is operated bya handle 0 of the T-pattern attached to its upper end.

In the modified form of my stop-pin shown in Fig. 7 the pin is attached to an angular segmental lever P, that is notched about its periphery, as at p. This notched end of said lever works through aslot in a stop-plate 1), whereby any one of the notches may be sprung into engagement with the said plate and thus adjust the position of the pin and r the quantity of liquid pumped.

In the modified form of spout shown in Fig. 8 the same is constructed in two parts R and R. The part B is attached to the pump-cylinder in the described manner,while the part R slides upon the said part B, packing-nuts r and r being attached to the re- The nut r is provided with peripheral recesses r into which are sprung teats r formed on the inner surface of the longitudinally-movable part B, to hold the spout in its closed position. A screw 1' is provided in part B to lock the two parts in their adjusted positions. It will be observed from the above that the spout may be extended at will in a telescopic manner.

In the modified form of the spout shown in Fig. 9 I have provided a rotatable mouthpiece S, that is adapted to be turn ed up toprevent the spout from dripping. This mouthpiece is screw-threaded and is adapted to be screwed upon screw-threads 8, formed on the spout proper, and abut against an annular shoulder s, also formed thereon. Notches s are formed in said annular shoulder and are adapted to be engaged by the extended end 5 of the spring 8 that supports the spout-cover s.

In Fig. 6 I have shown the pump-cylinder attached to the cover by means of a screwthreaded lug T, integral therewith and en- IIO gaged bya thumb-bolt siwhereb y it is secured in position.

It will be observed from the above that when the piston is drawn up the liquid in the can rises through the pendent tube, and as the piston is forced downward is forced out through the delivery-spout. The exact amount desired is secured by limiting the upward movement of the piston by means of the adjustable stop-pin, the farther the pin being moved in the less the movement will be, and vice versa.

A suitable bail Q can be applied to the can for carrying the same.

It will be observed that all the several parts may be taken to pieces to permit a thorough scouring of the same and as readily put together again. To assist in this cleaning operation, I have provided a circular brush U, Fig. 10,having a screw-threaded socket adapted to receive the end of the rod E when it is removed from the agitator. The brush when thus applied to the rod is employed for clean ing the tubes.

The joints between the ground valve-seat and the delivery-tube may be made flat and packed with a suitable packing q, Fig. 12, any good and well-known packing being employed.

The T-handle for operating the piston or the agitator may be used in any of the modified forms of my invention. In thiscase the annular supporting-recess q for the fiat seat is formed with an outwardly and downwardly inclined bottom, which prevents the valveseat from pressing in upon the valve when pressureis appliedfrom above upon said seat. The joint between the cylinder and the pendent tube, as shown in this figure, is also provided with a flat valve-seat g and packing g the whole being secured together by screws.

It is sometimes desirable to apply my invention to a refrigerator. In such cases I employ buttons V, such as shown in Fig. 11, to secure the top of the pump-cylinder in the top of the refrigerator.

The discharge end of the delivery-spout is provided with the usual air-vent, so that the liquid will flow freely therefrom.
